<h2>Introduction</h2>
<p>Express.js has become the de facto standard for building web applications with Node.js. At its core, routing is one of the most fundamental concepts you need to master.</p>
<h2>Basic Route Structure</h2>
<p>Express routes follow a simple pattern that combines HTTP methods with URL paths:</p>
<pre><code>{`
app.get('/users', (req, res) => {
res.send('Get all users');
});
`}</code></pre>
<h2>Route Parameters</h2>
<p>Dynamic routes can be created using parameters:</p>
<pre><code>{`
app.get('/users/:id', (req, res) => {
const userId = req.params.id;
res.send(\`Get user \${userId}\`);
});
`}</code></pre>
<h2>Middleware Integration</h2>
<p>Routes can include middleware functions for additional processing:</p>
<pre><code>{`
const authMiddleware = (req, res, next) => {
// Authentication logic
next();
};
app.get('/protected', authMiddleware, (req, res) => {
res.send('Protected route');
});
`}</code></pre>
